STVE GEROUX, OF CHICAGO, ILLINOIS.

MECHANISM FOR ADJUSTING TRANSOMS AND THE LIKE.

Application filed July 24, 1911.

To all whom it may concern Be it known that I, S'rvn GEROUX, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Mechanisms for Adjusting Transoms and the like; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numbers of reference marked thereon, which form a part of this specification.

The object of this invention is to afford a simple and easily installed mechanism for adjusting transoms, swinging windows and the like.

It is also an object of the invention to afford a constructionin which the operating device may be adjusted as desired to suit the space in which installed and to permit of ready actuation by rotation.

It is also an object of the invention to afford a construction in which transoms, swinging windows, or any related installations may be positively actuated and firmly held in adjusted position by means of mechanism concealed from View with the exception of a rotational element adapted for manual engagement.

The invention consists in the matters hereinafter described and more fully pointed out and defined in the appended claim.

In the drawings: Figure 1 is a fragmentary view in elevation of a transom showing the actuating means in dotted lines. Fig. 2 is an enlarged fragmentary vertical section on line 2-2 of Fig. 1. Fig. 3 is an enlarged fragmentary elevation on line 38 of Fig. 1. Fig. 4 is a section on line 4-4 of Fig. 2. Fig. 5 is a view of a transom or swinging window partly in elevation and partly in section. Fig. 6 is a section on line 6-6 of Fig. 5. Fig. 7 is a detail of the actuating nut or carriage.

As shown in the drawings: 1, indicates the side casing of a door frame; 2, the transom bar; 3, the door hinged in the frame, and 4, a transom hinged along its bottom rail to the transom bar to swing inwardly in a familiar manner. Journaled in the frame between the side casings, is a worm shaft 5, having a knurled head or knob 6, secured on the outer end thereof and in the room from which it is desired to operate the transom. Secured on said worm shaft is a Specification of Letters Patent.

nut 7, provided with a slot in one side thereof, in which engages a pin or stud 8, secured on a plate 9, journaled in the jamb 10, of the frame. As shown, said plate is engaged rotatabl'y in place by means of a stud screw 11, which threads into the hub 12 of a base plate 13, as shown in Fig. 4, said hub extending into the jamb, and said plate having peripheral spurs 14, thereon, which, when driven in the jamb, as shown in Fig. 4, act to rigidly hold the same from rotation while permitting the plate or wheel 9, to rotate freely thereon. Secured on the inner side of said j amb above the transom bar, is a plate 16, which may be provided with an integral hub extending through the jamb similar to the hub 12, before described. J ournaled in the bore of said hub is a shaft 17, having crank arms 18 and 19, respectively, rigidly secured on opposite ends thereof in any suitable manner.

As shown in Figs. 2 and 3, the ends of the shaft are angular to engage in suitable apertures therefor in the end of the crank arm, though, of course, other means may be employed for afiording the connection, if desired. The outer end of the crank arm 19, is pivotally engaged with one end of a link 20, to the inner end of which is secured a shaft 21, which is journaled in a bearing box 22, secured on the rear side of one of the side rails of the transom. As shown, the crank arm 18, is provided at its extremity with a wrist pin 23, on which is engaged the upper end of a link 24, the lower end of which is lingitudinally slotted. As shown, a wrist pin 25, is secured on the plate or wheel 9, and j ournaled thereon is a link 26, corresponding with the link 24, and the upper end of which is also longitudinally slotted. Bolts 27 extend through said slots and rigidly but adjustably engage the ends of said links together to afford a continuous adjusting bar. It is obvious from the c011- struction described that a plurality of small windows or transoms 4, may be operated simultaneously by extending the shaft 17, and engaging a plurality of crank arms 19, and links 20, thereon.

The construction illustrated in Figs. 5, 6, and 7, is identical in all respects with that before described with the exception that in stead of plate or wheel 9, a bell crank 28, is provided, one end of which engages the lower end of the link 26, while the other end is provided with a pawl shaft 29, which engages in the slot in the nut or carriage 7. As shown also in this construction, the transom or swinging Window is journaled upon trunnions and 31, secured on opposite sides or opposite ends thereof at the middle. The trunnion 31, is provided at its inner end (which entends through the jamb) With a crank arm 33. The upper end of the link 24:, is engaged on the extremity of said crank arm to rotate the same.

The operation is as follo'ivs: hen it is desired to open the transom or to swing the Window, as the case may be, the knob 6, is rotated thereby rotating the Worm shaft, causing the nut or carriage to move longi tudinally thereof, thus rotating the bell crank 28, or plate 9, and causing c'orre spending movement of the crank arm 19 or 33, thereby swinging the sash in either direction, dependent upon the direction of rotation of said shaft. In adjusting the device, the length of the actuating rod aflorded by the links 26 and 24, is varied to suit the requirements of the installation. This may be accomplished by simply loosening the bolts 27, to adjust said links relatively to each other and When adjusted,- to again rigidly secure the same in unvarying relation by means of the bolts.

Of course, details of the construction may be varied, and I do not purpose limiting the patent to be granted on this application otherwise than necessitated by the prior art.

I claim as my invention:

In a device of the class described, the com bination With a hinged member and a support therefor, of actuating means comprising a compound lever, an adjustable connecting rod for actuating said lever, a rotatable plate to which the other end of said connecting rod is pivoted eccentrically, a hubbed pivot plate secured in the support with the hub extending therein, a stud shaft for said rotatable plate pivoted in said pivot plate, and a worm actuating traveling nut engaging a stud on said rotatable plate and adapted to actuate said rotatable plate.

In testii'n'ony whereof I have hereunto subscribed my name in the presence of two subscribing Witnesses.

STVE GEROUX.
